[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1 to 6 As shown, an ultra-small flexible circular neon light strip with no dark areas and no light spots includes an upper light strip 100 and a lower light strip 200 arranged symmetrically at the top and bottom.

[0025] The bottom of the upper light strip 100 and the bottom of the lower light strip 200 are attached to each other to form a circular or elliptical light strip.

[0026] The upper light strip 100 includes an upper FPCB3, an upper LED light-emitting chip 2, and an upper diffusion adhesive 1. The upper LED light-emitting chip 2 is disposed on the upper FPCB3, and the upper diffusion adhesive 1 is disposed on the upper FPCB3. The upper LED light-emitting chip 2 is located inside the upper diffusion adhesive 1. The upper diffusion adhesive 1 is semi-circular or semi-elliptical, and the left and right sides of the upper diffusion adhesive 1 are wider than the upper FPCB3.

[0027] The structure of the lower light strip 200 is the same as that of the upper light strip 100. The lower light strip 200 includes a lower FPCB, a lower LED light-emitting chip, and a lower diffusion adhesive. The lower LED light-emitting chip is disposed on the lower FPCB, and the lower diffusion adhesive is disposed on the lower FPCB. The lower LED light-emitting chip is located inside the lower diffusion adhesive. The lower diffusion adhesive is semi-circular or semi-elliptical, and the left and right sides of the lower diffusion adhesive are wider than the lower FPCB.

[0028] The width of the upper diffusion adhesive 1 is 0.5 mm to 1 mm larger than the width of the upper FPCB 3, and the width of the lower diffusion adhesive is 0.5 mm to 1 mm larger than the width of the lower FPCB.

[0029] If the width of the upper FPCB3 is 3mm, then the width of the upper diffusion adhesive 1 is 3.5mm to 4mm, but not limited to this.

[0030] The upper diffusion adhesive 1 is a fluorescent powder adhesive, and the lower diffusion adhesive is a fluorescent powder adhesive.

[0031] The ultra-small flexible circular neon light strip with no dark areas and no light spots also includes a transparent heat-shrinkable film 4, which wraps the light strip.

[0032] The ultra-small flexible circular neon light strip with no dark areas and no light spots also includes a silicone neon tube sleeve 5, which wraps the transparent heat-shrinkable tubing film 4.

[0033] The diameter of the silicone neon tube sleeve 5 is less than 12mm.

[0034] The diameter of the silicone neon tube sleeve 5 is preferably 8mm, but is not limited thereto.

[0035] The bottom surface of the upper FPCB3 of the upper light strip 100 is attached to the bottom surface of the lower FPCB of the lower light strip 200. The edge arc corner 1-1 of the upper diffusion adhesive 1 of the upper light strip 100 is squeezed and bent between the upper FPCB3 and the transparent heat shrink tubing film 4. The edge arc corner of the lower diffusion adhesive of the lower light strip is squeezed and bent between the lower FPCB and the transparent heat shrink tubing film.

[0036] The ultra-small flexible circular neon light strip with no dark areas and no light spots also includes a sleeve end plug 6, a sleeve inlet end plug 7, and a power cord. The sleeve end plug 6 and the main sleeve inlet end plug 7 are respectively connected to the two ends of the light strip, and the power cord is electrically connected to the light strip.

[0037] This utility model provides an ultra-small flexible circular neon light strip with no dark areas and no bright spots. It uses two 3mm wide upper light strips 100 and 200 (such as COB light strips), with their bottom surfaces adhered together to form a circular or elliptical shape. Specifically, when applying the diffusion adhesive or fluorescent powder to the 3mm wide upper light strip 100 and 200, the adhesive or powder is intentionally applied wider than 3mm, resulting in a total width of approximately 3.5mm to 4mm. Then, the two 3mm wide upper light strips... The upper LED strip 100 and the lower LED strip 200 are bonded back-to-back, then covered with transparent heat-shrink tubing. This heat-shrink wraps the upper LED strip 100 and the lower LED strip 200, bending the rounded edges of the diffuser adhesive on both sides towards the FPCB board, forming a circular or elliptical shape. When the upper LED strip 100 and the lower LED strip 200 emit light, the light is fully diffused through the upper diffuser adhesive 1 (including the rounded edges 1-1 after bending) and the lower diffuser adhesive, achieving no dark areas and no bright spots. Then... The silicone neon tube sleeve 5 is wrapped to create an ultra-small flexible circular neon light strip with no dark areas or light spots, which can be achieved by wrapping it with a 360-degree circular shape.

[0038] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
